We study the momentum correlation functions of \(p \Xi ^-\) and \(\Lambda \Lambda \) pairs produced in high-energy nuclear collisions by using the coupled-channel framework and the \(N \Xi {-}\Lambda \Lambda \) coupled-channel baryon-baryon potentials recently obtained from lattice QCD calculations at almost physical quark masses. The calculated results are found to well describe the correlation function data from pp and pPb collisions. This agreement confirms the \(S=-2\) baryon-baryon potentials from lattice QCD and supports the existence of the H dibaryon as a virtual state around the \(N \Xi \) threshold.

$$N \Xi $$ N Ξ 相互作用和寻找$$N \Xi $$ N Ξ 阈值周围的H 双重子态的飞秒研究

我们研究的动量相关函数\（P \僖^ - \）和\（\ LAMBDA \ LAMBDA \）通过使用联接通道框架和高能核碰撞产生对所述\（N \僖{ - } \Lambda \Lambda \)最近从几乎物理夸克质量的晶格 QCD 计算中获得的耦合通道重子-重子势。发现计算结果很好地描述了来自pp和p Pb 碰撞的相关函数数据。该协议证实了来自晶格 QCD的\(S=-2\)重子 - 重子势，并支持H双重子作为\(N \Xi \)阈值附近的虚拟状态的存在。
